Abstract
A display apparatus having a privacy mode and a sharing mode is provided. The display apparatus includes a display panel, a privacy liquid crystal module, and a touch sensing module. The touch sensing module is disposed on a side of the privacy liquid crystal module and is configured to generate a touch signal. When the display apparatus is in the privacy mode, the privacy liquid crystal module is applied with a first voltage. When the display apparatus is in the sharing mode and the touch sensing module generates the touch signal, the privacy liquid crystal module is applied with a second voltage for a predetermined time. After maintaining for the predetermined time, a third voltage is applied to the privacy liquid crystal module. The display apparatus can effectively reduce a smear phenomenon caused by the display apparatus being touched in a sharing mode.
